How Are FRP Tanks Made?

May 25, 2023

Fibre-Reinforced Plastic (FRP) tanks have gained popularity across industries due to their exceptional strength, corrosion resistance, and versatility.

In this article, we’ll take you through the manufacturing process of FRP tanks.

From raw material selection to the creation of the product, you’ll begin to understand why FRP products are a superior choice.

1. Raw Material Selection

The manufacturing process of FRP tanks begins with the careful selection of high-quality materials.

These typically include fiberglass reinforcements and a thermosetting resin.

Fiberglass reinforcements provide the tanks with strength and rigidity, while the thermosetting resin acts as a binder, ensuring excellent corrosion resistance.

2. Mold Preparation

Preparing the mold is a crucial step in manufacturing FRP tanks.

The mold determines the tank’s shape and dimensions and is typically made from fiberglass, steel, or aluminum.

Meticulous cleaning and treatment of the mold ensure proper release and a smooth surface finish.

3. Layering and Resin Application

Layering is a critical step in FRP tank manufacturing.

Pre-cut fiberglass reinforcements, shaped according to requirements, are carefully positioned within the mold.

The number and arrangement of these layers depend on the tank’s intended use and desired strength. After layering, the thermosetting resin is applied to saturate the fiberglass fully and ensure a strong bond.

4. Curing Process

Following the resin application, the curing process begins.

The tank is subjected to heat and pressure, allowing the resin to harden and bond with the fiberglass reinforcements.

Curing is vital for achieving the desired strength and durability of the final product. The duration of the curing process varies based on the tank’s size and complexity.

5. Trimming and Finishing

Once the tank has cured, it is carefully removed from the mold.

Any excess fiberglass is trimmed, and the surface is prepared for finishing touches.

This may involve sanding, buffing, or applying a protective gel coat to enhance appearance and UV resistance.

Benefits of FRP Tanks

– Superior Corrosion Resistance: FRP tanks offer exceptional resistance to corrosive chemicals. This makes them ideal for industries such as chemical processing, water treatment, and oil and gas.

– Lightweight and High Strength: Despite their lightweight nature, FRP tanks exhibit remarkable strength and stiffness. Compared to traditional materials like steel and concrete, FRP surpasses in due to it’s high strength-to-weight ratio.

– Customization Options: FRP tanks can be easily molded into various shapes and sizes, allowing for customization to meet specific project requirements. This versatility makes them suitable for both above-ground and underground installations.

– Longevity and Low Maintenance: FRP tanks have a long service life, often exceeding 30 years with minimal maintenance. This translates into cost and time savings compared to alternative materials.

The manufacturing process of FRP tanks involves meticulous raw material selection, layering, resin application, curing, and finishing.

The resulting product offers numerous benefits, including superior corrosion resistance, lightweight construction, customization options, and low maintenance requirements.
